A couple of days ago our sensors picked up two separate malicious email campaigns, both impersonating Data Processing Services, that upon successful client-side exploitation (courtesy of the Black Hole Exploit Kit), drops an identical piece of malicious software.
Let’s dissect the campaigns, expose the malicious domains portfolio, connect them to previously profiled malicious campaigns, and analyze the behavior of the dropped malware.

A cybercriminal/gang of cybercriminals that we’ve been closely monitoring for a while now has just launched yet another spam campaign, this time impersonating the “Data Processing Service” company, in an attempt to trick its customers into interacting with the malicious emails. Once they do so, they are automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
In this post, I’ll profile their latest campaign and the dropped malware. I will also establish a direct connection between this and three other previously profiled malicious campaigns, as well as an ongoing money mule campaign, all of which appear to have been launched by the same cybercriminal/gang of cybercriminals.
